There are many types of camellias, some hardier than others. To protect the flowers from frost-thaw damage, position the plants away from full early morning sun and drying winds.
I have a small camellia, bought from local co-op for £1.99 three years ago. I read up on it and thought it doesn't stand a chance in caithness, but it proved me wrong, earlier this year it flowered. I gave it no special treatment, but do have it in a pot.
